5 Claims. 1

This invention relates to a self-closing faucet composed of screw machine parts, a tube and a spring. Specifically the invention deals with a self-closing faucet especially adapted for barrels or drums wherein the nozzle of the faucet can be rotated to any desired position and can be locked in open or closed position by means of an attached device avoiding the necessity for a padlock.

While the invention will hereinafter be specifically described as embodied in a self-closing barrel or drum faucet, it should be understood that the invention is not limited to any particular usage since the principles of this invention deal generally with valve or faucet constructions.

According to the invention a one-piece body member is easily formed on a screw machine from hexagonal bar stock. The body member has a threaded end portion for threadedinsertion in the plug of a drum or barrel. The hexagonal shape of the bar stock affords a head adapted to be engaged by a wrench to tighten the threaded end in the barrel or drum. The body has stepped bores therethrough with a shoulder between the bores. A tube slides in the smaller bore. A positioner member is telescoped on the tube and brazed thereto to slide in the larger bore. This positioner member has annular grooves therearound. A spring is compressed between the shoulder and the positioner member to urgethe tube for moving a seal ring carried on the end of the tube against the end of the threaded portion of the housing. A lever member is pivoted on the body and fits in a slot provided therein to seat in one of the grooves of the positioner thereby locking the faucet in opened or closed positions. This lever is locked against swinging movement by means of a pointed screw threaded axially into the end face of the body and accessible only :by means of a special tool. The screw and lever therefore cooperate to provide a lock forthe faucet thus avoidin the necessity for additional padlocks or the like. The end of the tube carries a sealing rin and has ports therethrough adjacent the sealing ring so that when the tube is depressed into the housing against the spring pressure to move the sealing ring away from the body, these ports are exposed to permit flow of fluid through the tube. V

A featureof this invention resides in the use of a single device attached to the body of the faucet for locking the faucet in closed position and for holding the faucet in a selected opened position. 1

A further feature of the invention is the provision of a readily replaceable rubber or rubberlike sealin ring on the tube to seal the faucet in closed position whereby a type of seal ring materialv best suited for the fluid being handled by the faucet can be selected.

An object of the invention is to provide a selfclosing faucet having a nozzle that can be rotated to any desired position and held in open or closed position by an attached lever member.

A still further object of the invention is to provide a self-closing barrel type faucet that can be threaded home in the screw plug of a barrel or drum and still have the bent nozzle end thereof positioned as desired relative to the barrel.

A further object of the invention is to provide a self-closing faucet which is easily held in open position with an attached lever member.

A further object of the invention is to provide a self-closing barrel-type faucet which can be locked with an attached lever member, thereby avoiding the necessity for a padlock.

A still further object of the invention is to provide a self-closing faucet having selective degrees of opening.

Another object of the invention is to provide a faucet with a rotatable nozzle that can beturned up to prevent dripping.

Other features and objects of the invention will be apparent to thoseskilled in the art from the following detailed description of the annexed sheets of drawings which, by way of preferred example only, illustrate one embodiment of the invention.

On the drawings:

Figure 4 is a view similar to Fig. 3 but illustrating the faucet in fully opened position.

Figure 5 is a view similar to Fig. 3 but illustrating the faucet in partially opened position.

Figure 6 is a transverse cross sectional view taken along the line VIVI of Fig. 5.

Figure 7 is an exploded longitudinal cross sectional view, with parts in elevation, illustrating the manner in which the parts of the faucet of this invention are assembled.

As shown on the drawings:

As shown in Figs. 1 and 2, the faucet Ill of this invention is mounted on a metal drum I I, such as an oil drum. The drum II has a head or end face IIa which, as shown in Figs. 3 to 5, is. equipped with an internally threaded boss I ll) re ceiving the faucet.

The faucet Ill includes a body I2 slidably sup porting a tube I3 providing the faucet'nozzle. This tube I3 is closed by a disk I4 which carries a removable sealing ring or washer I5. A metal washer I6 overlies the removable sealing washer I and receives a cap screw I! therethrough which is threaded into the disk I4 to retain the washer in position. A locking washer I 8 is interposed between the washer I6 and head of the cap screw II. A spring I9 is provided in the housing I2 and acts on a positioner tube telescoped on the tube I3 for moving the sealing washer I5 against the end of the body I2 to close the tube. A pusher plate 2I is mounted on the tube I3 in front of the positioner 26. The plate 2I is adapted to be manually grasped for depressing the tube I3 into the housing to space the sealing washer I5 away from the end of the housing and thereby open the faucet. A lever member 22 is pivoted on the housing I2 and is adapted to coact'with the positioner 20 to hold the tube I3 in a desired opened or closed position. A pointed set screw 23 is threaded in the end face of the housing I2 and coacts with the lever 22 to lock it in position. The locking screw 23 is of the socket head type and is actuated by a socket head screw driver 24.

The body member I2 is preferably composed of hexagonal bar stock and is readily lathe turned to provide the desired shape. As shown the body has a tapered threaded end portion I2a adapted to be screwed in the boss Ill). The end of the threaded portion 2a is provided with a beveled end face I2b forming a seat for the sealing washer I5. A cylindrical bore I20 is provided in the threaded end portion of the body and extends to a shoulder IZd in the body. A larger bore I2e extends from the shoulder I2d through the front face of the body. The exterior of the body can be further lathe turned to produce a cylindrical portion I2f between two unturned hexagonal heads I29 and I271. The head I2b is adjacent the threaded end I2a and is adapted to be engaged by a wrench or other turning tool for rotating the body to thread the end In into the boss I ID.

The head I29 is at the front end of the body and has a slot I22 cut through one side thereof to communicate along this side with the bore I2e. The lever 22 fits in this slot I2i and is pivotally connected to the body by means of a pin 25. As shown the groove I2z' is in one of the top side walls of the hexagonal body I2 and the pin extends through the groove and through the lever 22 at the lower end of this top side wall. The lever is somewhat longer than the side wall and when seated in the groove projects beyond the body as shown in Fig. 2. The lever has a depression 22a in its front face adapted to receive the screw 23. This screw 23 as shown is threaded through the front face of the body at the upper end of the side wall containing the groove and is accessible only by means of a wrench for its socket head.

The tube I3 has slots I3a cut inwardly from the end thereof containing the closure member It to provide opposed ports in the end of the tube. The opposite end of the tube is bent at I32) to provide a nozzle. The end of the nozzle por- 4 tion I3b is inclined at I30 to have its forward edge lower than its rearward edge thereby preventing formation of a bubble or film across the mouth of the nozzle.

The closure member I4 as best shown in Fig. 7 has a peripheral groove Ida adapted to receive the end edge of the tube I3. The closure memher It is brazed to the end of' the tube and a brazed bond 26 is shown in Figs. 3 to 5 to illustrate the integral connection between the closure member and the tube. The rear face of the closure member I4 also has a peripheral groove I412 therearound for receiving the sealing ring I5. The sealing ring I5 projects radially beyond the periphery of the closure member I l and the washer IE is bottomed on the closure member I4 but projects to the outer diameter of the sealing rin for backing up the ring when it is seated on the face I2b of the body.

The positioner 20 is a cylindrical lathe turned tube with a plurality of peripheral grooves Zea, 29b and 200 therearound. Each of these grooves is adapted to selectively receive the lever 22.

The positioner 2i] slidably fits in the bore I2e of the housing and its end face provides a shoul-' der 20d in the housing. The spring I9 is mains tained under compression in the bore I2e of the housing between this shoulder 26d and a sealing washer 2! bottomed on the shoulder I2d. This sealing washer 21 snugly fits around the tube I3 and prevents leakage from the bore I2c into the bore I26.

The pusher plate 2| is bottomed on the front face of the positioner tube 20 and is a flat plate with radially extending arms 2Ia providing faces adapted to be readily engaged by the thumb for opening the faucet. A brazed bond such as 28. integrally unites the positioner tube 28 and the pusher plate 2i with the tube I3.

As shown in- Fig. 3 of the drawings, the spring I9 when expanded forces the tube [3 toward the front face of the body I2 to seat the sealing washer I5 against the seating face I2b of the body. The end of the tube is thereby sealed and the faucet is in closed position. In this position the groove 20d of the positioner 20- is aligned with the slot I22 and if it is desired to lock the faucet in closed pesition the lever 22 isswung into the groove I2i to seat in the groove 20a of the posi tioner. The lever 22 will cooperate with the groove 20a to prevent shifting of the tube I3 and to hold the tube in its closed position. If it. is desired to fixedly lock the lever 22, the locking screw 23 is driven home into the notch 22a of the lever by means of the driver 24 and the lever is retained in the slot I22 in its locking position. Since the screw 23 has a socket head retracted into the end face of the body I2, it can only be rotated by a socket head driving tool and the tool 24 thereby serves as a key for the device- The faucet thus has an attached lock avoiding the necessity for'apadlock. V

Asshown in Fig. 4 the faucet I0 is fully opened by pushing the" pusher plate 21 toward the front face of the housing I2 to compress the spring I9 and to align the groove 20a of the positioner 20 with the slot I21. The locking lever 22 is then dropped into this groove 20c and the faucet is held in fully opened position. In this position the ports or slots [3a of the tube project beyond the body I22 into the. drum II and a free drain-- age path is provided through the tube.

If it is desired-to drain the drum I I at a slower rate than the full capacity of the faucet. ID, the tube I3 can be held in a position between'the 5.. fully opened position of Fig. 4 and'the fully closed position of Fig. 3 by aligning the groove 20b of the positioner 20 with the slot Zflz' and by dropping the lever 2-2 in this groove as shown in Fig. 5. In this position the ports [3a of the tube are only partially projected into the'drum to give drainage outlets of smaller area than the full capacity of the ports.

The positioner 20 therefore not only looks the faucet in closed or selaed position to prevent unauthorized drainage of the; drum but also holds the faucet in selected open position. If the looking lever 22 is swung to the dotted line position shown in Fig. 2, the spring l9 will maintain the faucet in closed position but it can be held in the desired depressed position by manual force on the pusher plate to drain the drum at a selected rate.

From the above description it will be understo'odthat the body of thefaucet' of this invention can be readily formed by screw machine operations on hexagonal bar stock. It will also be understood that the positioner 20 for the tube l3 can be formed on a screw machine. The tube I3 in turn can be conveniently bent from regulation tube stock. The other parts are easily stamped or coined. The faucet parts are assembled by brazing the pusher plate and positioner tube on the tube I3; by brazing the closure plu 14 into the end of the tube; by telescoping the spring l9 and sealing washer 21 around the tube and by inserting the assembly through the housing. The sealing washer l and backing up washer l6 are then mounted on the closure plug I 4 and the assembly is held together in assembled relation. The sealing washer I5 is readily removed and replaceable with a desired type of washer depending upon the type of fluid in the drum.

As shown in Fig. l the faucet Ill can be driven home in the boss of the drum without regard to the position of the nozzle l3c of the tube since the tube can be rotated into the desired position. This rotatable feature makes possible the positioning of the tube end as shown in dotted lines in Fig. 1 to prevent drippage.

The lever 22 and associated screw 23 provide a look without necessity for an added padlock.

It will, of course, be understood that various details of construction may be varied through a Wide range without departing from the principles of this invention and it is, therefore, notthe purpose to limit the patent granted herein otherwise than necessitated by the scope of the appended claims.
